A 13-year-old boy raped another “small and vulnerable” 12-year-old boy in a park as he walked to school.

The teenager was found guilty of holding the younger child against his will for half an hour, attacking him and forcing him to perform sex acts on him in May.

The horrifying attack happened in Roe Green Park in Brent, west London. Investigators believe the younger child could have been targeted because he was small for his age.

The suspect released the younger boy after abusing him. The victim shared his ordeal with his teachers in school who then informed the police.

The Willesden Youth Court heard yesterday that the attacker was late for school on the day of the incident and lied to his teachers that he was in the park with “friends” and that he “didn’t know where the time had gone.”

Since the crime involved juveniles and minors, the authorities can not release their identities and it can not be established if the boys attended the same school.

The suspect was determined through various means including the victim’s description of him matching the school’s CCTV footage. The victim also picked him in an identity parade. Finally, forensic samples later matched the attacker and the victim.

The evidence is so compelling according to the court that the guilt of the attacker is certain.

The suspect denied the charges, and refused to answer questions from police interviews as well as give evidence during his trial. He also requested for his family not to be present during the trial.

The teenager was found guilty of rape of a child under 13, inciting a child under 13 into sexual activity and kidnap.

He will be sentenced in October. His lawyer has requested for a psychiatric report.
